Does anyone know how aprox much lift the engine will accept before approaching trouble? I am aware on keeping extra clearance per cam card.

.525 seems to be the magic number. Always check to be sure, piston to valve clearance and spring retainer to valve guide clearance as well.

I've seen some have retainer to guide interference at .450 and some accept a little over .500 so there's really no hard and fast rule. You have to measure.
